Enum GradientSpace

Source
pub enum GradientSpace {
    Srgb,
    LinearRgb,
    Oklab,
}
Expand description

Colour space in which a gradient’s stops are interpolated.

The default is GradientSpace::LinearRgb: cheap, physically correct, and a clear win over naive sRGB interpolation. GradientSpace::Oklab is kept as an opt-in for brand gradients with high-chroma endpoints where even linear-light shows an undesirable darkening in the mid-point. GradientSpace::Srgb exists primarily to reproduce designs that were authored against it byte-for-byte.

Variants§

§

Srgb

Interpolate directly in sRGB gamma-encoded space. Cheap, but midpoints of saturated gradients look muddy.

§

LinearRgb

Interpolate in linear-light RGB. Default. Physically correct and fast.

§

Oklab

Interpolate in the Oklab perceptual colour space. Best for saturated brand gradients; slightly more expensive.
